Mechanisms and driving forces of Earth deformation, at length-scales from the tectonic to the microstructural. Introduces solid bodies, including stress and strain, with applications to plate tectonics, and surficial processes. Heat flow, electrical and electromagnetic fields are introduced, with applications to tectonic and hydrologic problems. (Normally offered fall semester). Prerequisites: 1000-level GEOL course with lab, PHYS 1110 or 1210.
